| 摘要: 合成和表征了5个螺旋配位聚合物{[Cu(Hbpma)(H2O)4]2(SO4)3·3.5H2O}n (1)、{[Ni(Hbpma)(H2O)4]4(SO4)6·10.75H2O}n (2)、{[Mn(Hbpma)(H2O)4](SO4)1.5·3H2O}n (3)、{[Zn(Hbpma)(H2O)4]4(SO4)6·4H2O·4CH3OH}n (4)和{[Cu(Hbpma)2(H2O)2](SO4)2·9H2O}n (5),其中bpma代表N,N'-双(3-吡啶甲基)胺。晶体结构分析表明配合物1~4为一维链状结构,配合物5为二维层状结构,其中金属离子由质子化的bpma配体桥连。值得注意的是,采取反-反式构象的柔性bpma配体使得配合物1和2为假螺旋链结构,配合物3和4为螺旋链结构,配合物5为螺旋层结构。同时研究了配合物的磁性和热稳定性。 | |

| Abstract: Five helical coordination polymers {[Cu(Hbpma)(H2O)4]2(SO4)3·3.5H2O}n (1), {[Ni(Hbpma)(H2O)4]4(SO4)6·10.75H2O}n (2), {[Mn(Hbpma)(H2O)4](SO4)1.5·3H2O}n (3), {[Zn(Hbpma)(H2O)4]4(SO4)6·4H2O·4CH3OH}n (4) and {[Cu(Hbpma)2(H2O)2](SO4)2·9H2O}n (5) (bpma=N,N'-bis(3-pyridylmethyl)amine) were synthesized and structurally char-acterized. The single-crystal X-ray analyses indicate that complexes 1~4 crystallize in the one-dimensional chain structures and complex 5 shows the two-dimensional layer structure, in which the metal ions are bridged by the protonated bpma ligands. It is noted that the flexible bpma ligands with the trans-trans conformation lead to the pseudo-helical chains for complexes 1~2, the helical chains for complexes 3~4 and a helical layer for complex 5. The magnetic properties and the thermal behavior are investigated. CCDC: 966929, 1; 966932, 2; 966930, 3; 966931, 4; 1054736, 5. | |
